This is a small tip which shows you how to know an IP address of a given domain name. The commonly used way is command ping. Let's have a look to how it works.

PING ( 56(84) bytes of data.

I can alternatively use another way to do that by using command host as the following


Output: is an alias for has address

The second way is a DNS lookup utility which is not only tell you what is IP address but also related alias around.

Security fixes, memory issues, better Vista support and several new languages are new features in Firefox which was released yesterday (May 30, 2007). It is available for downloading and installing.

VMware Inc today released version 6 of its industry-leading virtualization product VMware Workstation. VMware Workstation runs under a wide range of Linux and Windows versions and allows installation of an even wider range of guest operating systems within virtual machines. Among many possible applications are letting help desk personnel easily keep different Windows versions at hand, testing new software products under a variety of environments, and analyzing malicious software without the risk that it might damage a physical computer. Version 6 adds full support for Windows Vista both as host and guest along with significant feature enhancements from the previous version.

With this version, VMware's support for Windows Vista moves from "experimental" to mainstream. It fully supports all aspects of Vista inside a virtual machine except for the high-end graphics. At this time it doesn't provide the 3D graphics support necessary for Vista's Aero Glass display mode. However, VMware's senior director of virtual software lifecycle automation James Phillips said that this will change, as the necessary support is "in the lab" at present.

This version's support for multiple monitors is both powerful and flexible. The user can configure a single virtual machine to span multiple monitors or assign each monitor to a separate virtual machine. Long-time users will be pleased with the new virtual USB 2.0 ports--no more annoying "This device can perform faster" messages. The product currently has the ability to "clone" a virtual machine, producing either an independent duplicate or a space-saving duplicate that stores only what differs from the original. New in version 6 is the ability to clone a physical computer, quickly replicating the system as a virtual machine.

In addition, it adds remote-access capability based on VNC (Virtual Network Computing). The user must actively enable this feature--it's off by default for security--and allows authorized users with proper credentials to operate a virtual machine remotely without installing any additional software within the VM. As Phillips pointed out, VMware is already completely in control of the virtual machine's input and output, so going remote is just a short step.

VMware Workstation 6 makes new strides in integration as well. Software developers using Microsoft's Virtual Studio or the open-source Eclipse development platform now can compile a new build and run it in an automatically-created virtual machine, thereby avoiding the risk that a program flaw could damage the system being used for development. And the programmer has full control via the integrated virtual debugger. The new version also supports paravirtualization using the industry standard Virtual Machine Interface 3.0. The guest operating system can get better performance by taking advantage of VMI. Ubuntu Linux is the first to offer this support; Phillips said that many others have expressed support and will be implementing it.

On the bleeding edge, this new version adds experimental support for full record/replay within a virtual machine. That means it can record every single event that affects the virtual CPU's operation and play back those same events to exactly duplicate, for example, an intermittent software problem. Phillips explained that this feature is entirely independent of which guest operating system is used. VMware Workstation 6 is available as an electronic download directly from VMware for $189.

Linux uses hard disk space called swap to write information it needs for accessing various temporary programs when system RAM is busy. Writing to hard drive is slower writing to RAM because the hard drive runs 100 times slower than RAM. Therefore, if your computer has much RAM (1G or more) why don't you tell your kernel about that because this helps your kernel using swap less and RAM more to speed up your system. Now, I will let you know how to reduce the tendency for the kernel to use the swap file.
Step 1: see what is the current value for setting
sudo cat /proc/sys/vm/swappiness
(It should give a number 60 here)
Step 2: change to a lower number
sudo sysctl -w vm.swappiness=5
Step 3: check again
sudo cat /proc/sys/vm/swappiness
(Now, it should give a number 5 here)
Step 4: append this line vm.swappiness=5 to file /etc/sysctl.conf

After reboot the new value (say 5) is kept as the default value. Enjoy it! You also read more to know how to disable IPv6 to speed up your Ubuntu Linux

Since most of us don’t use IPV6 networks, this setting can slow down communication throughout our network. Turning this networking feature off will speed up your system.

sudo gedit /etc/modprobe.d/aliases

Make a search this line: alias net-pf-10 ipv6
and replaced by this line: alias net-pf-10 off #ipv6

sudo gedit /etc/hosts

Comment out all the lines which has to do with Ipv6 in this file and save it then.
The final step is that you reboot the system to take effect.
Next post, I will show you how to reduce swapping to speed up your Ubuntu Linux

So far, I have provided different methods to write to NTFS partition in Ubuntu and to read Linux partitions from Windows. Now is the suitable time to know how to write to Linux partition from Windows.
First of all, I would like to thank Stephan Schreiber who has designed and implemented Ext2 Installable File System software. This freeware application provides Windows NT4.0/2000/XP/2003 with full access to Linux Ext2 volumes ( both read and write access). This may be useful if you have installed both Windows and Linux as a dual boot environment on your computer. Now, I will show you how to install this driver. Once this driver is installed on Windows, you can easily mount a Linux partition on your computer into Windows and assign a drive letter to it.

  • Download Ext2EFS
  • Double click on file Ext2IFS_1_10c.exe to setup the driver
  • Click "Next" on the welcome screen, check on square "I agree" and click "Next" twice
  • Name for your Linux volume, click "Next" twice again and click "Finish" finally
On my laptop, I have mounted Ubuntu Linux partition as a drive G.

In Windows, you open My computer and can easily see a drive G there. That is a mounted point to Linux partition.

This is the result which shows the Ubuntu file system on my XP operating system.
Now, all files in the Linux partition can be browsed, read and written to. Why don't you try it? It is free.

In last post, I told you how to use existing hot keys to save time. However, we can also create hot keys to run other applications in Ubuntu. For example, how can we create a hotkey to launch a new terminal? It is too easy to do that because Ubuntu has a built-in utility for assigning shortcut keys. Go to System -> Preferences -> Keyboard Shortcuts and .. I think that you know what to do now. In this case, I used F10 to launch my terminal.

There are several reasons you may want to create an archive of a file or directory. Here are some of the most common ones:
  • Archive and compress unused directories to conserve disk space
  • Create an archive of a directory and files before an upgrade allowing you to restore the original contents if there is a problem
  • Archive a directory before making any major changes
  • Create an archive to move several files and folders to another system as one
  • Create an archive as a means of software distribution
One of the most useful utilities for archiving a set of files and directories is tar.The following command is a basic way of archiving a directorynamed mydata into a tar archive file named vntutor.tar

tar -cvf vntutor.tar mydata
Then, you can also extract the archive into its original structure by using
tar -xvf vntutor.tar

Do you know that we have two modes to interact with the Operating System like Ubuntu? In the old days, CLIs (Command Line Interfaces) was only used to work on a Unix computer. Nowadays, we have GUIs (Graphical User Interfaces) in addition to Linux machines. GUIs make OS more user-friendly while CLIs help us work more effectively. So, please read these tips to know what is user-friendly vs control and options.
  • Using GUIs is easier but using CLIs is faster.
  • GUI consumes too much CPU and memory.
  • CLI is generally easier unless you can remember the commands and the options.
  • The Linux CLI is so much more powerful than the old DOS CLI.
The real determining factor in choosing interfaces is how they meet your requirements. GUIs are helpful for many tasks, but they are not good for all tasks. Therefore, I like both GUIs and CLIs. Linux is freedom. Yeah!

I has been working with Windows OS many years. I think that small tips are useful for Windows users who start learning Linux.
  1. Names and commands are case sensitivity.
  2. File name should not contain spaces.
  3. "/" is a root directory.
  4. File name starting with a dot "." is a hidden file.
  5. There are no DOS-style drive letters.
  6. A line starting with # is a comment.

As default Ubuntu has no password set for the root user. To gain root access you have to type in your own user password. This is the password you set for the first user while installing Ubuntu.

To manually set a password for the root user, type in the following in the shell:

sudo passwd

After that you are asked to type in the new root password twice. Finally, your root user has its own password.

If you are a newbie in Linux, I think that this book is useful for you at the beginning. First, I need to know what is Ubuntu and how to use it. Then, I play around with some basic applications offered as default applications in Ubuntu such as (a full office suite to create your documentation like MS Office in Windows), Evolution (to manage your E-Mail and calendars like MS Outlook), GAIM (to chat with your friends on MSN, AIM, ICQ, or Yahoo ), GIMP (to create graphics like Adobe Photoshop), Firefox (a nice web browser like IE), CUPS (a common Unix printing system to manage your print jobs), SAMBA (for interoperability), Rhythmbox (a music management application like Media Player), and a lot of funny games. It is enough for now.

Hello all,

How do I start writing for this bog? Just only one word ”Ubuntu”. I have installed the lastest version of Ubuntu, one of the most successful Linux distributions, on my old laptop. It is not difficult to setup this operating system. You can also do that by dowloading Ubuntu and read this guide to know how to setup Ubuntu 7.04 step by step.

The best thing I like is that I can play with LiveCD which is built to run only off the CD without needing to be installed, before I have a full installation. This is a good tool to know what are new features supported from the operating system. Moreover, it is also used to test hardware on your laptop. I have never seen this feature in Windows.

Great! It works well and now is the time to learn Linux.

Thanks Ubuntu team!
